One basketballer measures 1.07 metres. The other measures 1.1 metres. What is the difference in their heights in mm?

The difference in their heights is 30 mm.

To find the difference in their heights, we can subtract the height of the first basketballer from the height of the second basketballer.

Height of the second basketballer = 1.1 meters = 1100 mm
Height of the first basketballer = 1.07 meters = 1070 mm

Difference in height = Height of the second basketballer - Height of the first basketballer
= 1100 mm - 1070 mm
= 30 mm

Therefore, the difference in their heights is 30 mm.

To calculate the difference in their heights in millimeters (mm), we need to convert the height measurements from meters to millimeters and then subtract the two values.

First, let's convert the heights from meters to millimeters:
1.07 meters = 1070 millimeters
1.1 meters = 1100 millimeters

Now, subtract the heights to find the difference:
1100 mm - 1070 mm = 30 mm

Therefore, the difference in their heights is 30 millimeters (mm).
